摘要：
We study the short-time dynamics of the O(4) spin model in three dimensions. Following the heat-bath time evolution algorithm, we obtain the dynamic critical exponents y and z related to the second moment of the magnetization and to the time correlation length, respectively. We also compute the ratio between the static critical exponents beta and nu. Our results are compatible with the ones obtained from other approaches.
